| Abstract: | Measurements are reported on low frequency noise in Au-InP Schottky diodes after heating cycles. An 1/f noise component was dominant in annealing time range before 80 min. Observation of G-R noise spectra are achieved for long-term operations. Noise measurements between 77 K and 300 K have given the time constants and the activation energies of five trapping levels. The G-R processes are attributed to traps due to gold contamination in the depletion region. |
